Brief Summary:
It is the purpose of this study to attempt to determine if there is an immediate, measurable change in visual function as a direct result following a session of cranial osteopathic manipulation.

Condition or disease Intervention/treatment Phase
Visual Function Procedure: Cranial osteopathic manipulation Procedure: Sham/Placebo Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 29 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single
Primary Purpose: Treatment
Official Title: Effect of Cranial Osteopathy on Visual Function
Study Start Date : October 2001
Actual Study Completion Date : February 2002

Arm Intervention/treatment
Experimental: 1
Assessment for cranial strain patterns, followed by indirect osteopathic treatment of dysfunctions found on assessment, followed by reassessment.
Procedure: Cranial osteopathic manipulation
This treatment is performed by exaggerating the motion asymmetry with a minimum of pressure (a few ounces) and holding the position until the motion becomes symmetrical.

Sham Comparator: 2
Assessment for cranial strain patterns, followed by laying on of hands, followed by reassessment.
Procedure: Sham/Placebo
A laying on of hands with no treatment being performed.

Primary Outcome Measures :
  1. Accommodative system testing Visual acuity testing Stereoacuity testing Vergence system testing Pupillary testing [ Time Frame: Immediately after intervention. ]
